Abstract
The invention relates to a tool structure for machining thin-walled parts. The tool structure comprises a concentric jacket, a through hole and a counter bored hole are coaxially formed in the concentric jacket, an elastic jacket is coaxially mounted in the counter bored hole, and the end of a mandrel penetrates the elastic jacket and is coaxially mounted in the through hole. The tool structure is simple and convenient to mount, the thin-walled parts to be machined are effectively and integrally protected by the aid of the concentric jacket and cannot be radially stressed in machining, deformation is prevented, references of the thin-walled parts to be machined are effectively switched by the aid of the mandrel, the machining progress of the thin-walled parts is greatly improved, and production efficiency is increased.
Description
Technical field
The present invention relates to field, especially a kind of tool structure for processing thin-walled class part.
Background technology
At present, seal for extensive use in Hydraulic Field as this in seal casinghousing, because himself required precision is higher, its planform is unfavorable for the clamping of conventional brace, and this part belongs to thin wall component, and surface quality is had relatively high expectations simultaneously, therefore traditional fixture cannot meet its clamping, and for its machining benchmark of thin wall component, look for comparatively difficulty, that for large batch of part, produces certainly will waste time and energy, and has had a strong impact on the manufacturing schedule of enterprise.
Summary of the invention
The applicant, for above-mentioned existing issue, is studied improvement, and a kind of tool structure for processing thin-walled class part is provided, and has not only effectively realized the processing to thin wall component, and machining benchmark is looked for conveniently simultaneously, has greatly improved processing progress.
The technical solution adopted in the present invention is as follows:
For a tool structure for processing thin-walled class part, comprise concentric chuck, be positioned on concentric chuck and coaxially have through hole and counterbore, coaxial device elastic jacket in counterbore, described elastic jacket coaxial device are run through in described through hole in the end of mandrel.
Its further technical scheme is:
The periphery of chuck arranges flange with one heart;
Elastic jacket adopts elastomeric material to make, and the inside that is positioned at described elastic jacket has taper and connects perforate, and the angle [alpha] of the described taper through hole conical surface is 30 ° ± 1 °;
Mandrel comprises axis body, in the periphery of described axis body, extends to form the first boss and the second boss, at the circle centre position of described axis body, also has centre bore;
The diameter of the axis body of described mandrel equates with the aperture of through hole on described concentric chuck;
The diameter of described the first boss is less than the diameter of the second boss.
Beneficial effect of the present invention is as follows:
The present invention is simple in structure, simple installation, and with one heart the layout of chuck has effectively realized the Global Macros for the treatment of processing thin-walled class part, guarantee thin wall component to be processed add man-hour radial direction can be not stressed, prevent distortion; The layout of elastic jacket has effectively realized the stress protection for the treatment of processing thin-walled class part, because elastic jacket has good elasticity, is therefore difficult for piece surface to produce and damage, and does not have opposing stress, and utilizes the elasticity of self to decompose stress simultaneously; The layout of mandrel has effectively realized the conversion of thin wall component benchmark to be processed, has greatly improved the processing progress of thin wall component, has improved production efficiency.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
The present invention includes concentric chuck 1, as shown in Figure 1, in the concentric periphery of chuck 1, flange 103 is set.Be positioned at and on concentric chuck 1, coaxially have through hole 102 and counterbore 101, in the interior coaxial device elastic jacket 2 of counterbore 101, elastic jacket 2 adopts elastomeric material to make, as shown in Figure 2, the inside that is positioned at elastic jacket 2 has taper and connects perforate 201, and the angle of taper through hole 201 conical surfaces is 30 ° ± 1 °.As shown in Figure 4, Figure 5, elastic jacket 2 coaxial device are run through in through hole 102 in the end of mandrel 4.Mandrel 4 comprises axis body 404, in the periphery of axis body 404, extends to form the first boss 401 and the second boss 402, at the circle centre position of axis body 404, also has centre bore 403.The diameter of the axis body 404 of mandrel 4 equates with the aperture of through hole 102 on described concentric chuck 1.The diameter of the first boss 401 is less than the diameter of the second boss 402.
Concrete assembling process of the present invention is as follows:
As shown in Figure 3, thin wall component 3 to be processed there is inclined-plane 301, in the inside of described thin wall component 3 to be processed, shoulder hole 302 is set, first the end of mandrel 4 run through and stretched out thin wall component 3 to be processed, and the end face of the second boss 402 of mandrel 4 and the bottom surface of the shoulder hole 302 of described thin wall component to be processed 3 are connected, as shown in Figure 5, then at the concentric inner coaxial device elastic jacket 2 of chuck 1, the inclined-plane 301 of the thin wall component to be processed 3 with mandrel 4 is stretched into the interior also laminating each other of taper through hole 201 of elastic jacket 2, make the end of mandrel 4 stretch in the through hole 102 of concentric chuck 1 simultaneously, realized thus concentric chuck 1, elastic jacket 2, mandrel 4 and thin wall component to be processed 3 coaxially arranged, then by after concentric chuck 1 device is on lathe, and take the center of circle of mandrel 4 and can realize the processing for the treatment of processing thin-walled class part 3 as benchmark.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention is referring to claim, and without prejudice to basic structure of the present invention in the situation that, the present invention can do any type of modification.
